* In his ClariSonus post John Atwood raises the very good question as to why I blog using the name Pliable, so it is worth providing the backstory in brief. After my corporate days were passed I worked for the UK criminal justice agencies on communication projects in the areas of race and equality. To avoid any conflicts between my employment and blogging, the latter does touch on humanitarian issues, I adopted the name Pliable from the character in Bunyan's Pilgrim's Progress. A lot of posts were uploaded using that identity and it seemed confusing to change identity mid-stream. But for several years I have been free of potential conflicts of interest, and there has been no attempt to conceal that this blog is written by Bob Shingleton.
